But they who only live to pamper up
Their flesh, when their possessions they have wasted,
Become bad citizens; for still unchang’d
Doth their voracious appetite remain.

[καὶ µὴν ὅσοι µὲν σαρκὸς εἰς εὐεξίαν
ἀσκοῦσι βίοτον, ἢν σφαλῶσι χρηµάτων,
κακοὶ πολῖται· δεῖ γὰρ ἄνδρ᾽εἰθισµένον
ἀκόλαστον ἦθος γαστρὸς ἐν ταὐτῷ µένειν.]

Euripides (485?-406? BC) Greek tragic dramatist

Barnes frag. 54, Musgrave frag. 7. (Source (Greek)). Alternate translation:

Indeed all who live life for big muscles, if their
wealth should fail, are bad citizens; for when a man becomes
accustomed to habits of gluttony, he remains in those habits.
[tr. Will (2015)]
